To all whom it may concern:

Be it known that I, EDWARD a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have .invented a certain new and useful Apparatus for 'lreating `Ai/Vaste, of which the following is a speciflcation.

My invention relates to an apparatus for treating animal and vegetable refuse, and in general, kitchen and table waste. of any kind.

What is commonly considered worthless and useless garbage, is in reality food stud of nourishing quality, articularly for poultry and hogs, but un er present practices,

other refuse, and there allowed to undergo various st-ages of fermentation, which is especially favorable for the engenderment and propa ation of the dangerous toxic germs. The diseases of fowl and swine, in particular, are largely, if not solely, attributable to this character of decomposed or partially putrilied waste, so also a great many dis eases caused in human beings by the consumption of iesh contaminatedl with Vinfectious matter.

This invention, therefore, is directed, first, toward the preservation vof 4the nutritious elements of the` waste, including the organic salts; second, toward the sterilization of these waste products; third, toward the obtainment of purified food stuff, in a homogeneous mass, free from unassimilable matter, and containing the essentials of nutritive aliments, such as animal and vegetal proteids, and finally, toward the recovery of the valuable animal and vegetal oils, which are ordinarily cast away.

With these and other objects in view, this invention, consists of thefeatures, details of construction and combination of parts described in connection with the accompan ing drawings, and then more particulerly pointed out' in the claims.

The drawing illustrates a sectional elevation showingL the vat and the grinder.

The a paratus consists of a vat 1, into which die waste material is delivered through an inlet 2, provided with avalve 2, a deflector 3, being stationed in proximity to said inlet to cause the material to be deposited approximately centrally of said vat. Within said chamber or vat, are disposed a t). EMERY,

plurality of perforated pipes 4, which are connected to a manifold 5, riveted to the to Patentes .rancia raie. i

of said vat, and to which manifold steam 1s supplied through a pipe 6, provided with a cutoff valve 6. The vat 1s bolted to the flanges 7,' of a casing 48, containing a' gate valve 9. Leading fromvsaid casing 8," at a point above said gate valve, are a plurality of pipes 10, furnished with a valve 1Q', which pipes serve to convey the liquids in the garbage to a settling and collecting tank 11, to be more fully described hereinafter. Connected with said main steam pipe 6, and with said casing 8, is a pipe 8', which, when the valve 8, thereon is opened, admits steam to the lcasing to loosen up the material, which by reason of its Weight might become congested and choke the passage way of the casing 8. The valve casing 8, 1s mounted on and fastened to a housing 12, composed of two sections, A and B, secured together at their peripheral edges, and whose interior coniguration is substantially conical. The underside of the section A, of the housing is provided with a plurality of acuminate ribs 12', while the section B, which. is sup-` .with the acuminate ribs 12, of the section A., in grinding the mass' as it gravitates from above, and in centrifugally discharging the ground mass through the opening 19, in one-.side of the housing. -Said cone is revolved by a bevel gear 20, mounted on a shaft 21, which is screwed in said cone, and

a bevel gear 22, meshing with said bevel gear 20, the driving gear 22, being mounted on a shaft 23, to which motion is imparted through any convenient source of power. ln order that some of the ground pulpl may not ooze into the bottom of the section B of the housing, and into the tray 24, pro-v vided in said bottom section, the periphery 25, of said cone is arrangzd to operate in a recess 26., formed in the ousing 12. Thus, while water may escape from the cone into the tray, the ground material cannot, but is i e. e

centrifugally discharged through the ope'ning 19. The water is drained from the tray 24, by a pipe 27, which is connected to the outlet 28, in the tray, land which leads to the settling and collecting tank 11.

The fatty constituents of garbage, and the minute particles of animal and vegetal matter, which may be termed sludge or tankage, are carried to 'the settling tank l1, where they are recovered'for subsequent uses. This tank consists of a-receptacle provided with a hinged lid 29, onto which is fastened a vent-plpe 30, to carry off what odors may arise from the liquids therein deposited. When the'waterfrise" in said tank 11, above the goese-neck 31, of n outlet pipe 32, it flows off through the trap 33,

1n said pipe, whilel the globules of grease,

remain on the surface of the water, from which it is separated or skimmed. The loose, soft sediment of the liquid, which collects at the bottom of the tank, is removed through a door 34, after the supernatant waters have been let out through the discharge pipe 35, and this sediment is .athen used either in its natural condition or prepared for fertilizer.

When the vat 1, l waste material, the valve 2, on the inlet thereto, and the gate valve 9, in' the casing, are closed, while the valve '10', on the drain pipes 10, are opened to allow the water from the garbage to flow oli". When this is done, the valve 6, on the main steam supply p1 e 6, is opened. In this vat, therefore, t ev steam jets, issuing from the perforated pipes 4, produce a pressure on and keep the material in a state of violent agitation,.caus ing all ofthe waste to. be thoroughly infused with the steam, and at the same time maclerating it and destroying all decomposing animal life, without, however, cookmg or digesting it, and thereby causing the essential juices and salts to be dissipated -or extracted.

When the mass has been subjected tov pres- I sure and heat for a length of time sufficient to sterilize and purify the material, the

. valve 10', on the drain pipes 10, is opened,

andthe waters of condensation together with melted greases, fats and oils, and whatever else may be in fluid form, drained oft' and.

delivered to the settling tank 11, for subsequent recovery and use. Thereupon the gate valve .9, isopened and the macerated mass allowed to gravitate though the passage' way of the valve-casing 8,l eventually striking the apex of the cone 14, which is being revolved at a high speed. The softened portions of the priorly treated mass, are readily reduced to a pulpous condition lby the centrifugal force of the cone, and such waste 'as bones, gristle, and other hard materials found in garbage, are ground to a size slightly smaller than the outlet from has been charged with the the housing 12,'through-which all of the waste 1s discharged. At this-pointthe treated mass is ready for foodand may be de livered directly from the nozzle 36, 'into receptacles, which are then hermetically sealed.

What I claim, is
